I have a 2000 Civic ex coupe, I just rebuilt the D16Y8 VTEC with stock internals, I put a yonaka axel back on and I can hear it burble and pop a little between 3 and 4k rpms. I was wondering how I should go about making the pops louder, I have the stock ECU and I don't want to spend a ton right now just curious if there is a way to make them louder without upgrading my ECU.

 

Drive it through 4 feet of water. It will burble real good.

 

unplug a vacuum line

 

Take off your catalytic converter

 

Wait, seriously?

LORD GRANT ME PATIENCE.
LORD GRANT ME SYMPATHY AND COMPASSION.
LORD GRANT ME THE TOOLS REQUIRED TO ABSTAIN FROM BEATING THESE FOOLS.

On Honda-Tech I pray, Amen.

 

Look, I don't **** with vacuum lines, hate dealing with the ******* things ever since I worked on my friends' 300zx, I would never unplug one ***** nilly, I'm just surprised that would work, unless I'm being stupid and this is a joke, I'm new to the civic platform.

 

It's a joke.
"Pop and burble" tunes are one of the latest backwards and stupid car trends that have been going around. People making their cars as obnoxious as possible for street cred, intentionally making the car backfire with tuning. Basically intentionally working in poor ignition timing.
